SMOKE-DISCEARGING MEANS FOR LOCOMOTIVES AND THE LIKE.

Application filed October 11 To all whom it may concern:

Be it known that l, Luowre Sononnnn, railroad engineer, a citizen. ofGermany, and a resident of 23 Biinderstrasse, in the city of Herford, in/Vestialia, Germany, have invented certain new and usefulSmoke-Discharging Means for Locomotives and the like, of which thefollowing is a specification.

This invention has reference to improvements in means of discharging thesmoke from locomotives or from similar coal "fed engines or movingboilers to the outside, and thereby preventing the discharge of thesmoke into the sheds or enclosures in which such engines or boilers arehoused, and it particularly refers to novel means of tight eningconnection of the hood or similar appliance which is exchangeablymounted upon the end of the locomotive or boiler chimney, and toimproved means of l12Ll1 dling and operating the same. In devices ofthis kind, as heretofore in use a hood, tunnel or the like is made todescend upon the upper end of the chimney of the loco motive or the likehoused in a shed or the like, by means of rope, chain or the like, thehood or funnel being thereby seated upon the said chimney and causingthe smoke to be discharged into the surrounding casing from which it isdrawn oil into the chimney and into the atmosphere by a suitable flue orother passage. In order to prevent destruction or injuring of thelocomotive or of the hood or funnel, when the locomotive is run out ofthe shed, it has been usual to mount the hood, tunnel or the like, so asto be capable of swinging movement in the direction of travel inaddition to its vertical reciprocating movement, while the weight ofsaid hood or the like has been balanced by a counter weight suspendedfrom chains or ropes, and guided on rollers in the ordinary manner, aspecial. additional rope being employed for the raising and lowering ofthe hood, funnel or similar smoke escape.

This invention is intended to improve the means of suspension and theautomatic return oi the said smoke escape conduits into the inoperativeposition, and to provide im proved means for the guiding of said conduitin the surrounding casing, and for the tightening of the joint at itspoints of connection with the locomotive chimney, and for the preventionof the accumulation of 1922.

soot and the like and the consequent chok} ing up of the said smokeescape conduit.

With these and other objects in view only one flexible connection byrope or the like is employed for connecting the smoke conducting meanswith the counter weight and for the raising, lowering and rendering inoperative of the said conducting means, the said flexible connectionbeing provided with an automatically operating locking member. Thecasing surrounding said conducting means is laterally enlarged, and atits bottom it is provided with two substantially semi-circular flaps orlids adapted to yield upon the swinging movement of the smoke conductingmeans, hood, tunnel or the like, preferably only one of said lids beingvertically oscillated by the swinging of the hood.

My invention will be more fully explained by the aid of the accompanyingdrawing showing by way of example a form of embodiment of the principlesof the invention in Figure l as a side view of the entire device withconnections. Figure 2 is a horizontal section through the lower portionof the tunnel or the like and through the casing on the line AB ofFigure 1. Figure 3 is a fractional diagrammatic sectional view on theline C-D of Figure 2; and Figure l is a horizontal section through thecounter weight and its guiding means.

The hood is funnel shaped, and consists of a tube with lowersubstantially spherical enlargei'uent which latter is adapted to fitupon the locomotive chimney 8. Upon its outer surface the tunnel f isprovided on both sides with preferably U-shaped guides a into whichstuds m rigidly secured to the surrounding casing c are projectinglyengaged. The casing c, as shown in Figures 1 and 2 is laterally enlargedon both sides, and as a bottom closure it is provided with twosubstantially semi-circularly recessed lids or flaps To thefunnel-shaped casing 6 a smoke escape conduit is connected. which leadsinto the stationary chimney not shown. The smoke conduit may, of course,have any direction whatever. Thus, for example the said conduit may leaddirectly upwards into an individual smoke chimney, or into a smokeescape passage in common to a plurality of smoke discharging funnels orthe like. The top portion of the funnel f is connected to a chain orrope c which is passed on guide rollers and connected to the counterWeight 0 which is vertically reciprocated in a suitable guide 9. Thecounter weight 0 is heavier than the funnel f, so as to retain itnormally in the raised position (Figure 1). If the locomotive or thelike has been run into the shed or other building containing the smokecatching and directing device, so that the locomotive chimney is placedvertically below the funnel f, the latter must be lowered upon thelocomotive chimney by raising the counter weight 0. This is effected bymeans of a hand wheel (Z and a gear wheel connected therewith andengaging with a rack bar provided upon the counter weight. Any otherlifting means may, of course, also be employed.

At the upper end of the counter weight 0 a lever a is mounted which isloaded at one side by the weight I: and is fulcrumed at the point 9. Thelever a is integral with the pawl c adapted for engagement with arigidly mounted rack bar Z). Upon raising the counter weight 0 by meansof the hand wheel (Z until the funnel becomes seated upon the locomotivechimney s, the locking lever (4,2' remains at first out of engagementwith the rack bar Z). But upon continuing to raise the counter weight 0the rope or chain 'c is released from tension, and is caused to sag, andin consequence thereof the locking lever (4,6 is free to be swunglaterally by the action of the one-sided load 70, and the pawl 2' maynow become engaged with one of the teeth of the rack bar Z), asindicated in dotted lines. This causes the counterweight 0 to becomesuspended from the rack bar and thereby to be thrown out of operation.The smoke escaping from the locomotive chimney is discharged through thefunnel 7 into the casing e and thence through the channel or flue 10into the stationary chimney. If it is desired to interrupt the escape ofthe smoke and to disconnect the locomotive chimney from the funnel, itis only necessary to disengage the locking pawl 2' and the locking levera; the counter weight 0 becomes then free to operate, and lifts thefunnelf into its highest position.

The device is, moreover, adapted for automatic operation. Thus, if anengine is run out of the shed in the direction indicated by the arrowsthe chimney s will carry the funnel f with it to a certain extent, inview of the fact that the funnel is free to oscillate on the studs m,and in view of the corre sponding lateral enlargement of the casing.During this swinging movement the, lower closing flaps or lids it of thefunnel casing e are swung out of the way, and during their movement anyaccumulated soot will be simultaneously discharged. After the engine hasbeen run out to such a distance that it is out of engagement with thefunnel f the funnel is no longer supported upon the locomotive chimney,and by its own weight it causes the tensioning of the rope or chain onwhich it is suspended, and in consequence thereof the locking pawl 60,2'is moved into the position of disengagement, so as to lift the pawl 2'out of the teeth of the rack bar 5. I At this moment the counter weight0 which is heavier than the funnel will operate and raises the funnelinto the inoperative position. The device according to my inventionpresents a great many other advantages. As a result of its mode ofoperation the funnel'will always be compelled to be perfectly loweredinto close contact with the locomotive chimney, so as to insure therequired tight connection for the exclusion of the leaking of smoke,because, unless the funnel is completely lowered, so as to raise thecounter weight to the required height, the locking by the pawl lever00,71 cannot take place, inasmuch as this locking lever can only beoperated, provided the load i taken off the flexible connection betweenthe funnel f and the counter weight 0, that is to say, when the funnelrests upon the locomotive chimney with its full weight. No similarperfect sealing of the connecting joint with the use of only one rope orflex.- ible connection, as far as I am aware, has ever been produced inthe previous smoke catching and conducting means of the kind referredto.

It is obvious that my invention is capable of various modifications andalterations as the conditions of its application may require.
